Show detail of all non standard connections such as bracing connections, truss connections, moment connections and hanger assemblies and other non standard connections as requested by the Engineer/Architect..3 Erections drawings to be stamped by a qualified professional Engineer/Architect licensed to practice in the Province of Newfoundland and Labrador. The erection drawings are to contain a clause stating that the professional Engineer/Architect who stamped the erection drawings is responsible for all fabricator designed assemblies, components and connections required for this project..4 Drawings for all fabricator designed assemblies, components and connections are to be stamped and signed by the professional Engineer/Architect who stamped the erection drawings. 1.4 SAMPLES.1 Submit samples in accordance with Section Submittal Procedures. 1.5 DESIGN DETAILS AND CONNECTIONS.1 Design details and connections in accordance with requirements of CAN/CSA S16 and CAN/CSA S136 with CSA S136.1 to resist forces, moments, shears and allow for movements indicated..2 Unless noted otherwise on the drawings or in the specifications connection design is the responsibility of the structural steel fabricator. Fully detailed connections shown on the contract drawings including bolt and welded sizes are deemed to have been designed by the Engineer/Architect..3 If connection for shear only (standard connection is required):.1 Select framed beam shear connections from an industry accepted publication such as "Handbook of the Canadian Institute of Steel Construction"..2 If shears are not indicated, select or design connections to support reaction from maximum uniformly distributed load that can be safely supported by beam in bending, provided no point loads act on beam..4 For non standard connections, submit sketches and design calculations stamped and signed by qualified professional Engineer/Architect licensed in the Province of Newfoundland and Labrador.

3 Issued 2006/08/01 Section Structural Steel for Buildings Page 3 of SOURCE QUALITY CONTROL.1 If requested submit on certified copy of mill reports covering chemical and physical properties of steel used in this work. 1.7 QUALITY ASSURANCE.1 At least 2 weeks prior to fabrication of structural steel submit to Engineer\Architect a letter from the fabricators Welding engineer stating the Welding engineer is responsible for welding procedures and practices for this project as outlined in CSA S Provide certificate of Quality Compliance from steel fabricator upon completion of structural steel fabrication stating that the work has been designed and fabricated in accordance with the requirements of the contract documents..3 If requested, submit to the Engineer/Architect one copy of all approved welding procedures for this project. PART 2 PRODUCTS 2.1 MATERIALS.1 Structural steel: to CAN/CSA G40.20/G40.21 Grade as indicated 300W and/or CAN/CSA S Cold formed structural members: to CANCSA s Anchor bolts: to CAN/CSA G40.20/G40.21, Grade 300W..4 Bolts, nuts and washers: to ASTM A325M.5 Welding materials: to CSA W59 and certified by Canadian Welding Bureau..6 Shop paint primer: to CISC/CPMA2..7 Hot dip galvanizing: galvanize steel, where indicated, to CAN/CSA G164, minimum zinc coating of 600 g/m FABRICATION.1 Fabricate structural steel in accordance with CAN/CSA S16.1 and in accordance with approved reviewed shop drawings..2 Install shear studs in accordance with CSA W59..3 Continuously seal members by continuous welds where indicated..4 Provide holes in top bottom flanges for attachment of wood nailers.

4 Issued 2006/08/01 Section Structural Steel for Buildings Page 4 of SHOP PAINTING.1 Clean, prepare surfaces and shop prime structural steel in accordance with CAN/CSA S16 except where members to be encased in concrete..2 Clean members, remove loose mill scale, rust, oil, dirt and other foreign matter. Prepare surface according to SSPC SP 6..3 Apply one coat of primer in shop to steel surfaces except:.1 Surfaces to be encased in concrete..2 Surfaces to receive field installed stud shear connections..3 Surfaces and edges to be field welded..4 Faying surfaces of friction type connections..5 Below grade surfaces in contact with soil..4 Apply paint under cover, on dry surfaces when surface and air temperatures are above 5 C..5 Maintain dry condition and 5 C minimum temperature until paint is thoroughly dry..6 Strip paint from bolts, nuts, sharp edges and corners before prime coat is dry.
